Tanya Cushman Reviewer Imagine you work in a library,
2
and one day a van pulls up in front of your building,
3
several people get out, they come into your library,
4
and they show you a list.
5
And they say, according to our records,
6
you no longer have access to these 5,432 books.
7
They march into your stacks,
8
pull those books off the shelves,
9
load them in the van, and drive off.
10
What just happened?
11
It looks like theft, right?
12
Strangers coming unannounced into your library and making off with a significant chunk of your collection.
13
My name is Jeff Edmonds,
14
and I do work in a library.
15
I've been with the Penn State Libraries here well over half my life.
16
And I can tell you that as bizarre as that scenario sounds,
17
it plays out in essence every single day,
18
not only here at Penn State,
19
but at libraries all over the country as the result of the shift in our collections from books to e-books.
20
Quick show of hands, how many of you have ever purchased a book?
21
I hope everyone in the audience.
22
Now, how many of you have ever purchased an e-book?
23
Would it surprise you to learn that you didn't purchase an e-book?
24
That it's impossible to buy an e-book?
25
To understand why, we have to look at U.S copyright law.
26
Specifically, the part of the law that codifies what you can and cannot do with the book that you've purchased.
27
When you buy a book,
28
that book becomes your personal property.
29
You own it.
30
You can do whatever you want with it.
31
You can even resell it.
32
And if you do resell it,
33
you get all the money.
34
The copyright holder, be it the author or the publisher,
35
has no claim on that sale.
36
Now imagine if that were true for e-books.
37
Imagine if you could buy and resell an e-book the same way you can buy and resell a print book.
38
We all know that it's infinitely easier to create copies of and distribute copies of digital objects,
39
like an e-book, compared to a print object, like a physical book.
40
So as the internet became a thing,
41
publishers realized they faced a crisis.
42
If consumers could buy and resell e-books the same way we can buy and resell print books,
43
their profit margins would evaporate and the publishing industry would collapse.
44
So what did they do?
45
They made a very astute decision.
46
they decided to not sell ebooks.
47
So when you clicked on buy it,
48
what you were paying for was not that ebook.
49
You do not own that ebook.
50
You were merely buying a license to access that text.
51
Now if this distinction between buying
52
and owning outright a print book versus paying for a license to access an e-book seems minor to us as individual consumers.
53
For libraries, like the one here at Penn State where I work,
54
that collect millions of e-books,
55
this distinction has profound and unsettling implications.
56
Let's start with the sense of scale.
57
This is the library's catalog.
58
We currently have about 10 million items.
59
Of those, more than 6 million are online.
60
They're digital.
61
They're ebooks.
62
Fewer than 4 million are actual physical books in the stacks.
63
So already, the majority of our collections are online.
64
They're ebooks.
65
And because they're ebooks, they're not owned in the same way our print collections are.
66
They're subject to licensing.
67
And because they're merely licensed, they're subject to removal.
68
Every month, we're compelled to remove thousands,
69
tens of thousands, and some months even hundreds of thousands of e-books from our catalog.
70
This is the van pulling up in front of our building and making off with a chunk of our collection,
71
which begs the question, who's driving the van?
72
If libraries don't own and control their e-book collections, who does?
73
The simple answer is publishers.
74
And in the realm of scholarly publishing,
75
the kind of publishing that concerns us in an environment like Penn State,
76
there are five publishers that control the marketplace.
77
It's an oligopoly.
78
And because they control the marketplace,
79
they leverage their advantage in several different ways.
80
First, the cost of e-books is artificially high.
81
On average, it costs more to license an e-book than it does to buy a print book outright.
82
Second, the cost of ebooks over the past several decades has risen much faster than the rate of inflation.
83
Third, publishers compel libraries to sign contracts that include non-disclosure clauses so that we can't discuss prices with our peer institutions.
84
Penn State, for example, can't go to the University of Michigan or Rutgers or UCLA and ask,
85
how much did you pay for this package of e-books?
86
We have no way of determining what a fair market price is.
87
Fourth, publishers bundle their content together so that we're compelled to license thousands
88
and even tens of thousands of e-books that we neither want nor need.
89
Imagine you're in the grocery store and you go into the cereal aisle
90
and you pull your favorite cereal off the shelf and put it in your cart.
91
And a clerk at the end of the aisle says,
92
what are you doing?
93
You say, well, I'm buying this cereal.
94
And they say, no, no,
95
no, you can't do that.
96
Store policy is that you have to buy one of each.
97
It's absurd, right?
98
And yet that's what publishers are doing to libraries,
99
forcing us to end up with thousands of things we neither want nor need.
100
Now, this very uneven, unfair relationship becomes even more absurdist when you consider where the knowledge comes from that populates these e-books.
101
Who's creating this knowledge?
102
Well, in a word, we are.
103
This is how scholarly publishing works.
104
Scholars do research.
105
They write manuscripts.
106
Those manuscripts are passed to peers, who then make comments.
107
The comments are passed back to the authors,
108
who then revise their manuscripts to improve them.
109
And then ultimately, an editor or an editorial board decides that this manuscript is worthy of publication,
110
say as an ebook or as an article in a scholarly journal.
111
Now note that all of the intellectual labor I just described,
112
from start to finish, is done at universities.
113
The salaries of these people are paid for by universities.
114
And how are universities funded?
115
Well, three ways of primary importance.
116
First, First, tuition monies.
117
So if you're a student paying tuition,
118
your money is being used in part to fund this enterprise of knowledge creation.
119
Second, taxpayer dollars.
120
Like many institutions, Penn State is a public university.
121
We depend on money from the Commonwealth every year for our operating budget.
122
So here you have taxpayer dollars being used to fund this enterprise of knowledge creation.
123
Third, grant monies.
124
While some grants can originate from a private individual or private enterprise,
125
the vast majority have a strong publicly funded component.
126
So again, public funds being used to fund this enterprise of knowledge creation.
127
So we've funded this process,
128
we've done the work, we've created the knowledge,
129
and then what do we do with our manuscript?
130
We hand it off to one of these publishers,
131
who then license it back to us at enormous cost.
132
The libraries here at Penn State spent over 13 million dollars on ebooks and other electronic resources last year.
133
Even the dire straits in which higher education finds itself,
134
we know for example that Penn State just a couple of years ago was facing a $142 million budget deficit.
135
This ecosystem makes no economic sense.
136
It's a broken system.
137
What could we do to correct it?
138
Well, what if we thought of our knowledge,
139
the knowledge that we collectively fund and create,
140
not as a private commodity to be handed off to some third party,
141
but as a public good?
142
What if we thought of it in the same light that we think of good roads,
143
sound bridges, a dependable electrical grid, clean air, clean water?
144
What would that look like in practice in this context?
145
Well, first of all, we could say goodbye to these publishers.
146
They need us because we do all the work.
147
We don't need them.
148
Here's an example.
149
This is a scholarly journal known as Lingua.
150
It's published by Elsevier.
151
Elsevier is the largest of those five publishers.
152
Their profits last year exceeded $2 billion.
153
An annual subscription to Lingua costs a library over $2,500.
154
About a decade ago, the editors of Lingua,
155
led by the executive editor,
156
a Belgian linguist by the name of Johan Roerich, decided to walk.
157
They said goodbye to Elsevier because they were disgusted with its pricing models.
158
They left and they started their own journal, Glossa.
159
Same topic, linguistics, same quality, same editors.
160
Except, unlike Lingua, Glossa is free.
161
It's what we call open access.
162
Open access literature is literature that's freely available online and free of all or nearly all licensing restrictions.
163
If we expand that concept of open access to something else that's of vital importance to an environment like Penn State,
164
textbooks, we end up with what are called open educational resources or OER.
165
We know that the cost of textbooks has risen over a thousand percent in the past 40 years,
166
and the prices of textbooks continue to rise at a rate three times the rate of inflation.
167
Research we've done locally at Penn State has shown us that over half of Penn State students,
168
65% have elected not to buy a textbook because it was too expensive.
169
And nearly a third, 31%,
170
have elected not to take a course because the materials were too expensive.
171
This is the open textbook library in the library's catalog.
172
It's a collection of over 1,500 textbooks in all disciplines that are freely available online.
173
They're free and they're freely adaptable.
174
By that, I mean that
175
if a Penn State professor were to find a textbook in this collection that was perfectly suited to their course,
176
except for, let's say, two chapters,
177
they could remove those chapters or rewrite them and upload their version of the textbook
178
to make it freely available to their students.
179
As a sustainable model, this sure beats the heck out of asking every student in every section of those courses
180
to shell out 75 or 100 or $150 for a textbook that they will probably never use after that course completes.
181
If we expand that notion to its broadest possible application,
182
we end up with this.
183
For several years now, the libraries have been working assiduously to identify,
184
to locate, to make discoverable resources that are not controlled by publishers,
185
that are freely available online, free to read.
186
These are things that are not behind a paywall.
187
You don't need to authenticate as a Penn State user to look at them.
188
They will still be accessible to you after you leave Penn State.
189
In fact, they're accessible now to anyone with internet access.
190
The number currently stands at over 1,200,000,
191
and we expect to see this number rise as we continue our work.
192
As I said at the beginning,
193
I've been with the libraries for well over half of my life, over 35 years.
194
And I've come to believe that libraries are a fundamental pillar of democracy.
195
Democracy demands an informed citizenry.
196
And informed citizens must have free and equitable and open access to information and to knowledge,
197
especially the knowledge that we've collectively funded and created.
198
Knowledge is not a private commodity to be handed off to some third party.
199
Knowledge is a public good,
200
and it must be treated as such.
201
Thank you.

練習のコツ
このビデオの速度とトーンに合わせてシャドーイングを行うことで、効果的に英語力を向上させましょう。話者のペースに注意し、単語やフレーズを正確に再現することがポイントです。特に、shadow speechのテクニックを使い、モニターの発音やイントネーションに合わせて繰り返すことをお勧めします。もし最初は難しく感じることがあっても、shadowspeaksを取り入れることで、繰り返し練習が可能になるので、挑戦してみてください。
また、IELTS スピーキング対策としても、このビデオの内容を使って練習することができます。リスニングやスピーキング力を同時に鍛え、英語シャドーイングの効果を最大限に引き出すために、自分の声で話すことを意識しましょう。少しずつリズムに慣れてきたら、より自然に英語を話せるようになります。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
